ENGINES OVERVIEW

The Allis Chalmers 170 tractor, equipped with either a Perkins 3.9L or Allis Chalmers 3.7L 4-cylinder diesel engine, provides robust performance suitable for medium-duty agricultural tasks. The Perkins engine is known for its fuel efficiency and torque characteristics, making it advantageous for pulling heavier implements, while the Allis Chalmers engine may offer simpler maintenance and parts availability. However, users should consider engine durability and service support based on the chosen option, especially in remote areas.

ENGINE DETAIL 1

The Allis Chalmers 170 tractor features a Perkins 4.236 diesel engine, providing robust performance with a displacement of 236 ci (3.9 L) and a compression ratio of 16:1, ideal for efficient power delivery at a rated RPM of 1800. With a bore and stroke configuration of 3.875x5.00 inches, it offers a balanced torque curve, well-suited for demanding agricultural tasks. While the coolant capacity of 15 qts (14.2 L) indicates potential for effective heat management, attention to valve clearance maintenance (0.010 inches for both intake and exhaust) is critical for optimal engine performance and longevity.

ENGINE OIL 1

The Allis Chalmers 170 tractor has an oil capacity of 7 quarts (6.6 liters), which is relatively modest for a tractor of its size. This lower oil requirement can lead to easier maintenance and lower operating costs, but it's crucial to ensure regular oil changes to maintain engine performance and longevity. Operators should also be mindful of oil quality and viscosity, especially in varying temperature conditions, to optimize engine efficiency.

ENGINE DETAIL 2

The Allis Chalmers 170 features a G-226 4-cylinder engine with a displacement of 3.7 liters, providing robust torque at a rated RPM of 1800, which is suitable for fieldwork and heavy-duty applications. With an 8:1 compression ratio, it promotes efficient combustion, although users may face challenges in maintaining the specified clearances (valve and spark plug) for optimal performance. The tractor's liquid-cooled system, with a coolant capacity of 15 quarts, ensures effective thermal management, enhancing engine longevity and reducing the risk of overheating during prolonged operations.

ENGINE OIL 2

The Allis Chalmers 170 tractor has an oil capacity of 6 quarts (5.7 liters), which is relatively modest and facilitates easy oil changes and maintenance for users. However, it may require more frequent oil checks and top-ups during extended operations, particularly under heavy loads. Adequate oil filtration and regular servicing are critical to optimize engine longevity and performance given its oil capacity constraints.

ALLIS CHALMERS 170 ENGINES

The Allis Chalmers 170 tractor features either a Perkins 3.9L or an Allis Chalmers 3.7L 4-cylinder diesel engine, providing robust performance suitable for various agricultural tasks. The Perkins engine is known for its fuel efficiency and high torque output, while the Allis Chalmers variant may offer easier availability of parts. A potential challenge lies in engine compatibility and serviceability, as the Perkins option may require specialized maintenance compared to the more common Allis Chalmers engine.

TRANSMISSION

The Allis Chalmers 170 features a two-speed power shift transmission, allowing for efficient gear transitions with 8 forward and 2 reverse options. A notable advantage is the Power Director lever, which enables on-the-move shifting without clutching, enhancing productivity during field operations. However, the requirement to stop and use the dry disc clutch for selecting forward or reverse gears may hinder quick maneuverability in certain scenarios.

Transmission Power Director
Type two-speed power shift
Gears 8 forward and 2 reverse
Clutch dry disc
Oil capacity 24 qts/22.7 L
Description The transmission is controlled by means of the gear shift lever and the Power Director lever. The tractor must be stopped, and clutch used, to select one of four forward gears, or reverse. The Power Director lever has high, low, and neutral positions. The Power Director can be shifted on the move without clutching. Placing the Power Director into neutral causes the tractor to stop while keeping the PTO engaged.

MECHANICAL

The Allis Chalmers 170 features a robust 4x2 2WD chassis, providing better control on flat terrains but may struggle in soft or uneven ground conditions. Its hydraulic power assist steering enhances maneuverability, making it suitable for tight spaces during field operations. The 8-speed two-speed power shift transmission allows for versatility in speed and torque application, ideal for varied agricultural tasks, although the open operator station may expose the operator to the elements.

ALLIS CHALMERS 170 TIRES

The Allis Chalmers 170 tractor features a range of front tire options (6.00x16 to 9.00x10) suitable for varying agricultural applications, offering flexibility in ground engagement depending on the terrain. The 16.9-28 rear tires enhance traction and stability, particularly in heavier fieldwork scenarios such as plowing or tilling. However, the limited range of rear tire sizes may restrict adaptability to specialized implements, potentially affecting performance in specific tasks like row cropping or heavy-duty hauling.
